The primary object of the invention is to provide a heated road rollerin which the heating flames contact the surface of the roller within ahousing partially encompassing the roller.

Another object of the invention is to provide a heated road roller inwhich a housing encompasses a major portion of the roller and moves withthe roller.

A further object of the invention is to provide a heated road roller ofthe class described above in which liquified petroleum gas serves as thefuel for the roller contacting flames.

A still further object of the invention is to provide a heated roadroller of the class described above which is inexpensive to manufacture,simple to use and which provides a heated roller in an economicalmanner.

Other objects and advantages will become apparent in the followingspecification when considered in light of the attached drawings, inwhich:

FIGURE 4 is a fragmentary vertical sectional view taken along the line4-4 of FIGURE 3, looking in the direction of the arrows;

FIGURE 5 is a perspective view of the modified form of the invention;and

FIGURE 6 is an enlarged fragmentary bottom plan view of the structureillustrated in FIGURE 5.

Referring now to the drawings in detail wherein like referencecharacters indicate like parts throughout the several figures, thereference numeral it} indicates generally a power driven road rollerconstructed in accordance with the invention.

The road roller It} includes a frame 11 having an upwardly and forwardlyoffset gooseneck 12 integrally formed on the forward end thereof. Asteering wheel 13 is mounted on the frame 11 for steering the frame 11in the conventional manner.

A metal weighted roller 14.- is secured to the frame 11 by means ofbearing blocks 15 at opposite ends of the roller 14. The roller 14 isrotated by power means (not shown) under the control of the operator.

A yoke 16 is mounted under the gooseneck 12 and is controlled by thesteering wheel 13. A second road roller 17 is journalled on an axle 18supported in opposite ends of the yoke 16 so that the road roller 17 mayturn freely on its axis.

A housing, generally indicated at 19, has a flat, generally rectangulartop wall 20 positioned in overlying relation to the roller 17. A pair ofside walls 21 are arranged in vertically depending relation to oppositeside edges of the top wall 20 and are secured thereto. A front wall 22depends vertically from the front edge of the top wall 20 and connectsthe forward edges of the side walls 21. A rear wall 23 dependsvertically from the rear edge of the top wall 20 and connects the rearedges of the side walls 21.

A horizontal flange 24- extends inwardly from each of the side walls 21parallel to the top wall 20, terminating ice closely adjacent to butspaced from the ends of the road roller 17. The front wall 22 has arearwardly extending horizontal flange 25 formed on the lower edgethereof in parallel relation to the top wall 2t). The flange 25terminates adjacent the roller 17 but spaced therefrom. The rear wall 23has a flange 26 integrally formed on the lower end thereof extendingforwardly toward the roller 17, terminating closely adjacent to butspaced therefrom.

The fianges 25, 26 have a plurality of orifices 27 arranged in spacedapart relation therein.

The front wall 22 has an elongated slot 28 formed therein adjacent thetop wall 20. The rear wall 23 has an elongated slot 29 formed thereinadjacent the top wall 20. The end walls 21 are each provided with anelongated slot 3i) formed therein adjacent the top wall 2ft.

The end walls 21 are secured to the yoke 16 by bolts A and B as shown inFIGURE 4, or other suitable means, so that the housing 19 is supportedin rigid relation to the roller 17.

A liquified petroleum gas tank 31 is secured centrally on the top wall20 and is controlled by a conventional valve 32. A pipe 33 is positionedadjacent the tank 31, parallel to the top wall 20, and has its oppositeends supported in fittings 34. The pipe 33 is connected to the tank 31through a flexible hose 35. A pipe 36 extends transversely of the topwall 2% adjacent the front wall 22 and the rear wall 23. The pipes 36have their opposite ends supported in fittings 34.

A relatively short, vertical pipe 37 depends from each of the fittings34 and projects through the top wall 2%, as can be clearly seen inFIGURES 2 and 4. The liquid petroleum gas burner 38 is mounted on thelower end of each of the relatively short, vertical pipes 37 andpositioned so as to direct flames emitted therefrom toward the roller17.

The apertures 27 permit the influx of air into the housing 19 while theelongated slots 23, 29, 5t permit the products of combustion to bedischarged from the housing 19. The roller 14 is heated by a similarburner system so that both the roller l4 and the roller 17 will beequally effective when rolling bituminous road surfaces.

A modified form of the invention is illustrated in FIG- URES 5 and 6wherein a hand operated road roller is generally indicated at 5%.

The road roller 5d includes a generally cylindrical weighted roller 51mounted on an axle 52. A generally rectangular hollow housing 53 ispositioned in overlying relation with respect to the roller 51 and has atop wall 54, a pair of spaced parallel end walls 55, a front wall 56,and a rear wall 57. The side walls 55 each have an inwardly extendinghorizontal flange 58 integrally formed on the lower edge thereof andarranged parallel to the top wall 54. The flanges 53 terminate adjacentto but spaced from the opposite ends of the roller 51. The front Wall 56has an inwardly extending flange 59 integrally formed on the lower edgethereof and arranged parallel to the top wall 54. The flange 59terminates adjacent to but spaced from the roller 51. The rear wall 57has an inwardly extending flange 6t} integrally formed on the lower edgethereof parallel to the top wall 54, The flange 60 terminates adjacentto but spaced from the roller 51.

The side walls 55, front wall 56 and rear wall 57 each have an elongatedhorizontal slot 61 formed therein adjacent the top wall 54. The flanges59, 60 are each provided with a plurality of spaced apart apertures 62opening therethrough, for reasons to be assigned.

A yoke 63 is connected to opposite ends of the axle 52 and has a keyhandle 64 secured thereto and extending outwardly therefrom.

A plurality of spaced apart, arcuately arranged bores 65 are formed inthe side walls 55 to receive a coupling pin 66 extending through theyoke 63 to secure the yoke 63 to the housing 53 in an angularlyadjustable position with respect thereto.

The top wall 54 has a liquified petroleum gas tank 67 mounted thereonand controlled by a hand valve 68. A horizontal pipe 69 is connected tothe tank 67 and feeds gas therefrom to fittings 79 mounted on the topwall 54. A burner 71 is positioned within the housing 53 underlying eachof the fittings 7t and is supported thereby, receiving gas therefrom inthe same manner that the burners are supported and fueled by thefittings 34-, in the preferred form of the invention.

In the use and operation of the invention, the burners 71 are operatedin the same manner as the burners 38, with air being admitted to thehousing 53 through the apertures 62 and the products of combustion beingexhausted through the slots 61.

Although liquid petroleum has been described as a preferred fuel, itWill be understood that other types of fuel such as propane, butane,natural gas, kerosene, or the like may also be employed by appropriatemodification of the burner structure.

Similarly, while a particular shape and size of fuel tank is disclosed,modification in the shape, size and location, for the purposes ofbalance, may be made as long as the basic principle of a roller heatedfrom the outside and located within a hood to conserve the heat isadhered to.

Having thus described the preferred embodiments of the invention, itshould be understood that numerous structural modifications andadaptations including changes in size and body size may be resorted towithout departing from the scope of the appended claims.
